I'd suggest using some form of remote desktop to control the other PCs, then you don't need monitors and keyboards and can have access to them all from one central machine. "Pro" versions of Windows feature this built in if you enable it, but there are alternatives, e.g. Google has a free remote desktop system. You can move your one main monitor / keyboard / mouse to the machine for initial set up, then just leave it as a box on its own after that :)
For nodes, any hardware will do, personally I find refurbished dual Xeons to be good for price / performance, I went for older ones due to budget, but even a $500 machine can perform well. Graphics card is irrelevant, so you can go without if you get the option in the system you are buying, or go for the cheapest, as it has no role to play.
You will need Max installed on each node, but it doesn't have to be licensed - this means you can't run Max on the node (ie open it as a program and use it) but you won't need to. As noted, you will need an OS for each machine too of course.
Hope this helps!
